Answer» ANSWER: Rewrite the expression as ∫[(sec ² x) (sec²x)l) ] dx Recall that sec²x = 1 + tan²x.. Trig ID. Thereafter, replace 2 in 1, get ∫[(sec ² x) ( 1 + tan²x) ] dx Multiply the expression to get 1. ∫[(sec²x + sec²x.tan²x) ] dx Use SUBSTITUTION, say u = tanx .. du = sec²x and split into TWO integrals.. ∫ (sec² x + ∫sec². tan ²x) dx Integrate the expression with respect to x, we have ∫sec² x dx + ∫ (u)²du) = tanx + ⅓tan³x + c. Something like that

1.

Integral sec⁴x dx .solve it

Answer»

ANSWER:

Rewrite the expression as ∫[(sec ² x) (sec²x)l) ] dx

Recall that sec²x = 1 + tan²x.. Trig ID.

Thereafter, replace 2 in 1, get ∫[(sec ² x) ( 1 + tan²x) ] dx

Multiply the expression to get 1. ∫[(sec²x + sec²x.tan²x) ] dx

Use SUBSTITUTION, say u = tanx .. du = sec²x

and split into TWO integrals.. ∫ (sec² x + ∫sec². tan ²x) dx Integrate the expression with respect to x, we have ∫sec² x dx + ∫ (u)²du) = tanx + ⅓tan³x + c. Something like that

H.C.F. of X & Y and their product is 1280 , then Find L.C.M. of X & Y .

Answer»

⏺️ ⏺️ ⏺️ ⏺️ ⏺️ ⏺️ ⏺️ ⏺️

HCF of X and Y is 1280

X × Y is 1280

Therefore,

HCF × LCM = X × Y

1280 × LCM = 1280

LCM = 1

Hence, the LCAM of X and Y is 1.

8.	If 12th term of an AP is 82 and 18th term is 124 then find out 24th term
Answer» GIVEN: The 12th term of an AP = a12 = 82 The 18th term of an AP = a18 = 124 TO FIND: The 24th term of an AP SOLUTION: 12th term: a + 11d = 82 ---(1) 18th term: a + 17d = 124 ----(2) After subtracting both eq - (1) & (2), we get: -6d = -42 d = 42/6 d = 7 Common Difference = 7 Substitute common difference (d) in eq - (1) => a + 11(7) = 82 => a + 77 = 82 => a = 82 - 77 => a = 5 First term = 5 Now, 24th term = a + 23d = 5 + 23(7) = 5 + 161 = 166 THEREFORE, the 24th term is 166.

8.

If 12th term of an AP is 82 and 18th term is 124 then find out 24th term

Answer»

GIVEN:

The 12th term of an AP = a12 = 82

The 18th term of an AP = a18 = 124

TO FIND:

The 24th term of an AP

SOLUTION:

12th term:

a + 11d = 82 ---(1)

18th term:

a + 17d = 124 ----(2)

After subtracting both eq - (1) & (2), we get:

-6d = -42

d = 42/6

d = 7

Common Difference = 7

Substitute common difference (d) in eq - (1)

=> a + 11(7) = 82

=> a + 77 = 82

=> a = 82 - 77

=> a = 5

First term = 5

Now,

24th term = a + 23d

= 5 + 23(7)

= 5 + 161

= 166

THEREFORE, the 24th term is 166.

14.

the area of a rectangular land is 520 sq. unit if the breadth of a land is 20 unit then what will be its length

Answer»

SOLUTION :

$\bf{\red{\underline{\underline{\bf{Given\::}}}}}$

The AREA of a RECTANGLE land is 520 sq. UNIT,if the breadth of a land is 20 unit.

$\bf{\red{\underline{\underline{\bf{To\:find\::}}}}}$

The length of the land.

$\bf{\red{\underline{\underline{\bf{Explanation\::}}}}}$

Let the length of the land be r unit

We know that formula of the area of rectangle :

$\bf{\boxed{\bf{Area\:of\:rectangle=Length\times breadth}}}}}}$

A/q

$\mapsto\sf{520=r\times 20}\\\\\\\mapsto\sf{r=\cancel{\dfrac{520}{20} }}\\\\\\\mapsto\sf{\orange{r=26\:unit}}$

Thus;

The land of the length is 26 unit.

$\boxed{\begin{minipage}{6 cm} Formulas of rectangle : \\ \\ $ \sf{Perimeter=2(Length+Breadth)}\\ \\ \sf{Area=Length * breadth }\\ \\ \sf{Diagonal = \sqrt{(length)^{2} +(Breadth)^{2} }} $\end{minipage}}$

Answer» 1 ) Make a line perpendicular to line of 5 CM from the point x. Now the perpendicular line drawn will be equal to 4 cm. It is because it forms a rectangle being PARALLEL to the line of 4 cm. Now the small line made on 5 cm line due to intersection of the perpendicular line will be equal to 5 - 3 , i.e, 2 cm. Now applying Pythagoras to find x.

1 ) Make a line perpendicular to line of 5 CM from the point x.

Now the perpendicular line drawn will be equal to 4 cm. It is because it forms a rectangle being PARALLEL to the line of 4 cm.

Now the small line made on 5 cm line due to intersection of the perpendicular line will be equal to 5 - 3 , i.e, 2 cm.

Now applying Pythagoras to find x.

(2)² + (4)² = (x)²

4 + 16 = (x)²

x = √20 = 2√5 cm

Find the 7 rational numbers between -7/8 and 6/8 with method

Answer»

Find 7 rational no...

$\frac{ - 7}{8} \: \: and \: \frac{6}{8}$

$\frac{ - 7 \times 5 = - 35}{8 \times 5 = 40}$

$\frac{6 \times 5 = 30}{8 \times 5 = 40}$

$\frac{ - 35}{40} > \frac{ - 34}{40} > \frac{ - 3 3}{40} > \frac{ -32}{40} > \frac{ - 31}{40} >$

$\frac{ - 30}{40} > \frac{30}{40}$

hey mate here is ur answer =

3 can be written as LOG 10^3

substitute in the equation:-

log (y)^2=logx+log 10^3

Now using PROPERTY log a+log b=log AB

log y^2=log X(10)^3

cancelling log on both SIDES :-

y^2=1000x

HCF of X and Y is 1280

X × Y is 1280

Therefore,

HCF × LCM = X × Y

1280 × LCM = 1280

LCM = 1

Hence, the LCAM of X and Y is 1.
